However, the quantity of Carbon-14 was nearly doubled in the ’50s and ’60s because of the atomic bomb testings in those decades.

The answer to the problem of fluctuating amounts of this important isotope is calibration.

Libby and others (University of Chicago) devised a method of estimating the age of organic material based on the decay rate of carbon-14.

Carbon-14 is a radioactive isotope used to date organic material.

Its consistent rate of decay allows the age of an object to be determined by the proportion of carbon-14 to other carbon isotopes. Carbon-14 is also used as a radioactive tracer for medical tests.

The regular use of wipe testing, using a liquid scintillation counter, is the only way to insure that your work space does not contain low-level removable contamination.

The increased levels of CO² in the earths atmosphere have created a greenhouse effect which is warming the earth.
